Hi guys and gals, I emailed Apex direct to find out if my lowering springs from my old 1.4 fiesta silver would be ok to be put on my ST and they said the ST is not classed as a normal fiesta because of the 2.0ltr engine makes the car heavier. therefore they would not suggest putting the springs on! does anyone know if this is the case, or how much weight difference there is between the cars?
